Public interface example:

config > service > ies 100
    interface "int-gre-tunnel-public" create

    no shutdown

Private interface example:

config > service > vprn 200 customer 200 create
    route-distinguisher 64496:1
    vrf-target target:64496:1
    interface "int-gre-tunnel-private" tunnel create // Private if
        address 10.1.1.1/30
        ip-mtu 1476
        sap pxc-1.a:200 create
            ip-tunnel "gre-tunnel-1" create
                source 192.110.1.2
